The ITfFnShowHelp interface is implemented by a text service to enable the language bar to place a help command for the text service in the language bar help menu.
The ITfFnShowHelp interface has these methods.
The TSF manager obtains this interface from the text service by calling the text service ITfFunctionProvider::GetFunction interface with IID_ITfFnShowHelp.
The TSF manager obtains the help menu text by calling the text service's ITfFunction::GetDisplayName.
